Hilo side: Wave heights are forecast to be double to triple overhead in some spots today at good exposures along the northeast coast. The best spots could get up to 18 to 25 foot faces or more. North Kohala will be a bit smaller but still good size.
Kona side: Wave heights are expected to be ankle/knee high today.
South: Wave heights are expected to be ankle/knee high today.
Our current northwest pulse will be down to traces Wednesday. That same storm which generated the northwest pulse has re-intensified and brought a large north-northeast swell which is expected to peak Wednesday and remain solid through Thursday before fading through the second half of the work week. Another small northwest is due in Friday / Saturday.
Nothing significant expected out of the South Pacific any time soon.
Keep in mind, surf heights are measured on the face of the wave from trough to crest. Heights vary from beach to beach, and at the same beach, from break to break.
